OK, was playing around due to a post in another thread. Trying to get the dash battery meter to work again.
Just testing the green wire coming out of the DQ.
When the charger is plugged into 110v, the green wire goes to -98v (pack voltage)
When the charger is not plugged into 110v it goes to +98v (pack voltage)
Is this safe to plug into the Gems interlock green/red wire ??
I know that you need +72 on the Green/red wire to bypass the interlock (and this is 72v at all times even when the car is parked) but I was not sure that showing -72 was correct.
Also, with 98v being way over the 82-85v of a standard battery pack, do you think the extra voltage will cause an issue.

It’s fine.
Same voltage as when you jumper interlock wire to B+.

Thanks Dave, going to give it a shot.

When the charger is Energized it Opens up the Circuit. When the charger is not plugged in the Green Grounds Out and closes the Circut and allows you to start your car

Not exactly! The green goes to B+ when not plugged in.
It does open a relay as you explained, but opens the B+ circuit. When relay is closed, the red and green are connected.
